While this is quite true, they really do 'eat' everything. I had a goat eat a bag of cement and the cord from a telephone, in one night. (She got out of her pen one night and wrecked havoc on our barn)

My neighbors goat once at a box of staples, including the box. Also as a practical joke the son locked a goat in their parents room and proceeded to wreck the room, shred their blankets, and then eat half of the wallpaper off their walls. They were not amused.
